+# AI-powered language learning with pronunciation assessment
+
+[!INCLUDE [Feature preview](~/reusable-content/ce-skilling/azure/includes/ai-studio/includes/feature-preview.md)]
+
+Learning a new language is an exciting journey, and the Pronunciation assessment feature has made it easier than ever to improve your language skills. Get instant feedback on pronunciation accuracy, fluency, prosody, grammar, and vocabulary from your chatting experience.
+
+> [!NOTE]
+> The language learning feature currently supports only `en-US`. For available regions, refer to [available regions for pronunciation assessment](regions.md#speech-service). If you have any feedback on the language learning feature, fill out [this form](https://aka.ms/speechpa/intake).
+
+## Common use cases
+
+Here are some common scenarios where you can make use of the language learning feature to improve your language skills:
+
+- **Assess pronunciations:** Practice your pronunciation and receive scores with detailed feedback to identify areas for improvement.
+- **Improve speaking skills:** Engage in conversations with a native speaker (or a simulated one) to enhance your speaking skills and build confidence.
+- **Learn new vocabulary:** Expand your vocabulary and work on advanced pronunciation by interacting with AI-driven language models.
+
+## Getting started
+
+Currently, we provide a Chatting scenario to interact with the voice assistant. To practice speaking skills with a GPT-powered language teacher, you can explore the Chatting scenario.
+
+To get started with language learning through chatting, follow these steps:
+
+1. Go to **Language learning** in the [Speech Studio](https://aka.ms/speechstudio). 
+
+1. Decide on a scenario or context in which you'd like to interact with the voice assistant. This can be a casual conversation, a specific topic, or a language learning exercise.  
+

+   
+1. Press the microphone icon to start speaking naturally, as if you were talking to a real person. 
+

+
+   For accurate vocabulary and grammar scores, speak at least 3 sentences before assessment.
+   
+1. Press the stop button or **Assess my response** button to finish speaking. This action will trigger the assessment process.

+

+
+   The assessment report may include feedback on:
+   - **Accuracy:** Accuracy indicates how closely the phonemes match a native speaker's pronunciation.
+   - **Fluency:** Fluency indicates how closely the speech matches a native speaker's use of silent breaks between words.
+   - **Prosody:** Prosody indicates the nature of the given speech, including stress, intonation, speaking speed, and rhythm.
+   - **Grammar:** Grammar considers lexical accuracy, grammatical accuracy, and diversity of sentence structures, providing a more comprehensive evaluation of language proficiency.
+   - **Vocabulary:** Vocabulary evaluates the speaker's effective usage of words and their appropriateness within the given context to express ideas accurately, as well as the level of lexical complexity.
+
+    When recording your speech for pronunciation assessment, ensure your recording time falls within the recommended range of 20 seconds (equivalent to more than 50 words) to 10 minutes per session. This time range is optimal for evaluating the content of your speech accurately. Whether you have a short and focused conversation or a more extended dialogue, as long as the total recorded time falls within this range, you'll receive comprehensive feedback on your pronunciation, fluency, and content.
+
+   To get feedback on how to improve for each aspect of the assessment, select **Get feedbacks on how to improve**.
+

+
+    When you have completed the conversation, you can also download your chat audio. You can clear the current conversation by selecting **Clear chat**.
